When I use CTRL+C to Toggle Comment, the functionality is BROKEN if you perform the following sequence: COMMENT CODE(CTRL+SHFT+C), FORMAT (ALT+SHFT+F), COMMENT CODE(CTRL+SHFT+C).
Undo Comment is broken when there are spaces before the "#" character on a line:
# THIS IS A COMMENT
# THIS IS AN INDENTED COMMENT #This Type will not untoggle due to the preceeding spaces.
